*Discovery*

    The address and name of enabled devices within range can be
    discovered by other Bluetooth devices. Discovery can take some time
    to complete, given that radio communications is unreliable. The
    following displays address and name of all enabled devices nearby.

        from bluetooth import *

        print "performing inquiry..."

        *nearby_devices = discover_devices(lookup_names = True)*

        print "found %d devices" % len(nearby_devices)

        for name, addr in nearby_devices:
              print " %s - %s" % (addr, name)

        performing inquiry...
        found 2 devices
